Surly CC Complete & FSA MegaEXO compatibility

[kardisa]

I'm planning to use my Surly Cross-check complete for brevets here in Korea, and have come to the conclusion that a triple crank is a necessity. Although my stock bike does allow me to add a granny ring, it's a part that is impossible to find in-country and ordering it would take longer than I would like. My friend has a FSA MegaExo crankset for sale for a good price, so I was wondering if it was possible to swap that out for my Andel RSC6 crank with no extra upgrades. Any thoughts?

You will need a triple front derailleur and a megaexo bottom bracket (or Shimano external road). Possibly a longer chain as well.
